CHARLES H. CORNELL, OF VALENTINE, NEBRASKA.

RAILWAY-FASTENING.

To all whom it may concern:

Be it known that I, CHARLES H. CORNELL, a citizen of the United States, residing at Valentine, in the county of Cherry and State of Nebraska, have invented certain new and useful Improvements in Railway-Fastenings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to rail fastenings for railway tracks.

It has for its object to provide an improved fastening which is inexpensive and may be quickly adjusted because it does not require the use of screws, spikes or rivets.

Another object is to provide a fastening bolt which may be adjusted to have the proper clamping action and locked at that point even though the proper clamping point on any two bolts should not be the same.

Further objects of the invention will become apparent from the following description.

It is obvious that the construction of bolt illustrated and described herein as applied to railway rails and ties may also be used for securing parts of other metal construction work such as steel framework for fire proof buildings, steel bridgework, viaducts, etc. While I have herein illustrated and described an I-beam tie in connection with the practice of my invention, it should be understood that other styles of ties may be used. For instance, an ordinary wooden tie may be employed with a metal plate below it to be engaged by the lug on the locking bolt.

The invention contemplates the use of integl'al bolts provided with laterally extending lugs formed their lower ends and heads adapted to clamp upon a part to be fastened. The shanks of the bolts with their lugs are passed through key slots with said lugs engaging the under face of the part in which the slots are formed. If said under face is beveled, the turning of the bolts with their lugs riding up on said beveled surface, will give the desired clamping action. Where the lower face of the slotted part is not beveled, 1 provide the heads of the bolts with spiral carnshaped under faces which produce the desired clamping effect when said bolts are turned. it will be understood of course, that the spiral cam-shaped heads may be used when the surface of the slotted part engaged Specification of Letters Patent.

by the lugs is also beveled, the result being that the clamping action is obtained by turning the belt a much less degree than is required when either the lower face of the slotted part is not beveled or the under faces of the heads are not cam-shaped.

The invention consists further in the features of construction and combinations of parts hereinafter described and specified in the claims.

In the accompanying drawing, illustrating the preferred embodiment of my invention: Figure 1 is a broken side view of an I beam tie to which the rails are fastened by means of bolts made in accordance with my invention, also by means of integral lugs formed on the tie itself. Fig. 2 is a plan view. Fig. 3 is an end view showing a bolt provided with a cam-shaped head. Fig. 4 is an end view showing a bolt not provided with a camshaped head. Fig. 5 is a broken side view of a tie and rail fastened together with a modi fied construction of bolt provided with a series of notches in the edge of its head through vhich the locking pin is inserted into the extension of the key slot in the tie. Fig. 6 is a plan view thereof. Fig. 7 is a vertical section taken through the key slot. Fig. 8 is a sectional view on the line of Fig. 1, showing the position of the washer which locks the bolt in place. Fig. 9 is a detail View of the washer. Fig. 10 is a broken detail view of the lower end of one of the bolts which has its lug sharpened at the upper edge. Fig. 11 is a broken view looking at the under surface of the flange of the tie through which the lug projects and showing the radial grooves engaged by the sharpened lug, and Figs. 12 and 13 are side and cross sectional views respectively of the ends of two rails with their fish plates fastened together with bolts constructor'l in accordance with my invention.

lieferring particularly to Figs. 1 to 9 inclusive of the drawings, 1 designates an I beam tie of the usual construction having the under faces of its top flange beveled from the web outward. integral lugs 1, extending in the same direction, are preferably formed near the ends of the tie for engaging one side of the foot of each rail thereby reducing by-half the number of separable fastenings required. Said upper flange is provided with key slots 2 through which are passed the shanks 3 and radially projecting lugs 4 of the fastening bolts 5. The heads 6 Fix of said bolts are adapted to engage and clamp solutely necessary The under faces l lugs on the beveled upon the feet of the rails 7. of said heads may be spirally cam-shaped as at 8. The edge of the head of each bolt may be serrated as at 9 in Figs. 1, 2 and 3 and said bolts may be locked by having a portion of the washer 10 bent up to engage one of said serrations. Said washer is generally semi-circular in form and has a turned flange 11 at its edge which engages the edge of the foot of the rail and prevents the washer from turning. Part of said turned down flange is cut away as at 12 to permit the shank of the bolt to contact with the foot of the rail. Portions 13 may be cut from either or both ends of the washer for engagement with the serrations in the head. It should be noted that washers of different thicknesses may be used to take up wear and also to provide against the bolt being turned completely around before the proper clamping action is had, which would result in the lug coming up through the key slot.

Instead of the serrations, the head of the bolt may be provided with a series of radial notches 14 through one of which the locking pin 15 may be inserted into the extension 16 of the key slot. Because of the repetition of these notches at intervals in the head, one of them will always be in alinei'nent with the extension of the key slots when the bolt is set in clamping position. i t iile I have shown the notched head also provided with a spiral cam-shaped under face, it will be understood that this cam is not required when the under surface of the flange of the tie engaged by the lug on said bolt is beveled.

As shown in Figs. 10 and 11, instead of using the washer described for locking the bolt, the lug on the lower end of said bolt may be sharpened at the top as at 17 and adapted to engage one of a series of radial grooves 18 formed in the under surface of the flange of the tie around the key slot therein. It will be noted that as the bolt is turned and clamped the sharpened edge will be forcibly engaged with one of said grooves and effectually prevent the bolt from becoming loosened.

In Figs. 12 and 13, 19 designates the ends of the two rails which are supported by fish plates 20 tapered inpwardly as shown in Fig. 18. Key slots 21 are formed through the fish plates and the web of the rails. The bolts are preferably passed through said slots alternately from the opposite sides. The lug 23 of each bolt engages one of the fish plates While the head 24 of said bolt engages the other plate. Because of the beveled or inclined faces of the fish plates, the turning of the bolts produces clamping action thereon which forces them tightly against the sides of the webs of the rails. 1 have shown the heads of the bolts provided with spiral ca1nshaped inner faces 24 although this is not ab because the riding of the v surfaces of the fish plates which they engage might give all the clamping action that would be desired. The edges of the heads of the bolts are serrated as at 25 and washers 26 are arranged between said heads and the fish plates so that portions thereof may be bent out into engagement with the serrations, for locking the bolts in position. The low edges of the washers preferably rest upon the base flanges of the fish plates whereby they are prevented from tinning.
